DESPATCHERS TRAIN-CONTROLLING DEVICE.

. To all! whom it may concern:

following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to signals for use on railroads, and has specialreference to a signaling system to be used by train despatchers tocontrol trains passing over a track. I

' The principal object of the invention is to provide means whereby thetrain despatcher may release a semaphore arm to permit it to fall to aposition indicating that the train is to stop.

Another object of the invention is to pro vide a means for releasing thesemaphore arm which consists of a minimum number of parts, is thereforesimple in construction,

and is cheap to manufacture.

With these and ther objects in view the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction within the scope ofthe claims may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention. s In the drawing:Figure 1 is a front elevation of one of the signal posts, the view beingpartlyin section, Fig. 2 is a side elevation of the same, parts thereofbeing'shown in sect-ion, and Fig. 3 is an enlarged detail of thesemaphore lock.

Likereference numerals designate corresponding parts in all the figuresof the drawing.

The sig '1 is preferably mounted on a -pole 16. Upon this pole ismounted a casing 17 wherein is held a pair of magnets 18 arranged toactuate an armature 15,). which 4 is held to s ide between guides 20mounted on the sides of the casing 17. Formed in the "oottom of thecasing is a centrally disposed transverse slot 17*. The armature 19 isin the form of a rectangular bar, and is so lo- Spccification of LettersPatent.

cated in the casing that it extends in a direction substantiallyparallel to the railroad. Below the casing 17 is a sectional casing 21.and mounted on the pole adjacent this casing is a semaphore '22, theblade of which is provided with an extension 23. This semaphore is soarranged that when raised the extension 23 lies behind the armature It).The blade is further provided with an arm 24 whereon is uiounted a bar25 of suitable conductingmaterial,such as brass orcopper, and this baris insulated from the extension by suitable insulation 26 of vulcaniteor hard rubber, Within the casing 21 are connected contacts 27, whichare spaced apart and which lie in such position that when the semaphore.arm 22 assumes the stop position or the position indicating that thetrain is not to pass. the bar 25 will lie across the contacts 27.

In operation, the semaphore arm is normally disposed in the positionshown in full lines in Fig. In this position, the upper end of thesemaphore is disposed within the transverse slot 17 of the casing 17 andthe armature 1!) is disposed in advance of the extension 22-; of saidblade. and serves to lock said arm against downward movement. \Vhen itis desired to lower the arm 22, the electro-magnet lb is "energized fromany suitable source of electrical energy, and as a result. the armatureit) will be elevated between the guides 20 to a distance sutiicient topermit of the extension 23 sliding thereunder, the Weight of the arm 22being sufficient to cause said arm to assume its lowered position. asshown in dotted lines in Fig. 2. \Vh'en the arm is in itsloweredposition, the circuit (not shown) will be closed between the contact 25and the contacts 27.

llaviiigthusdescribed the invention, what is claimed as new, is:-'

l. A signal system including in combination. a casing. an electro-magnetdisposed within the casing, an: armature loosely mount-- ed upon thecasing below the magnet, guides tor the armature carried by the magnet,a support disposed below the. casing, a semaphore arm pivoted to thesupport; a stop projecting from the arm for engagement behind thearmature when said arm is up. and controlling means tor said magnet.

2. A signal system including in combination, a casing including a bottomhaving a centrally disposed transverse slot formed therein, anelect-ro-magnet disposed within the easing how the slot, longitudinallydisposed spliced guides depending from the magnet and disposed above andin spaced relation to the bottom of the casing, an armature looselymounted upon the bottom of the casing below the magnet and between theguides and extending on either side of the slot of said casing, asemaphore arm pivoted to the support and adapted when up to have 0 itsouter end disposed within the slot of the casing, a stop projecting fromthe arm for engagement behind the armature when said arm is up, andcontrolling means for said magnet.

In testimony whereof, I alfiX my signa- 15 ture; in presence of twowitnesses.
